Partical Filter Color Traking

利用matlab进行时域分析，本实验首录了三个音频。并编写程序求其特征值。特征值有平均值，整流平均值方差，标准差，方差，峭度，均方根，波形因子，峭度因子，峰值因子，脉冲因子，裕度因子。还有就是对音频进行自相关分析得出其波形图。(Use matlab time-domain analysis, the first experiment recorded three audio. Programming and seeking the eigenvalues. Characteristic values are averaged rectified mean variance, standard deviation, variance, kurtosis, RMS, crest factor, kurtosis factor, crest factor, pulse factor, margin factor. There is an audio self-correlation analysis of its waveform.)

做信号处理的时候经常会用到FFT，而MATLAB自带的FFT只能变换出一列系数，想做成频谱图还要自己加一部分，自己写了一个小程序，输入原始信号和采样率，可以画出标准的幅值谱和功率谱。(Do signal processing is often used when the FFT, and FFT MATLAB own transformation from a coefficient of only wanted to make Canada part of the spectrum but also their own, to write a small program, the input original signal and the sampling rate can be Draw a standard amplitude spectrum and power spectrum.)

It is one of the successful prediction algorithms to estimate frequently for unknown parameters with real time operation. The principle of Recursive Least Square depends on least square mathematical weighted. Also, Recursive Least Square can set the points to fit the curve.
